sperts car- I think your question underlines the need to have a good relationship with a quality affiliate manager, so you are not in a position of guessing. Although your fellow affiliates might keep the good campaigns close to them, almost every affiliate manager is paid to get the most traffic they can. So they should be motivated to tell you what the hot offers are, especially if they like you. A good affiliate manager will protect you from running trash/tests and make your efforts more profitable. It has been my experience, my biggest affiliates talk to me often to gather the latest info from almost daily. My struggling affiliates probably don't even know my name independent of the emails i send, or my IM pings.
I can tell you from my view point- clever clasp is still a strong offer, but it is not as hot as it was a couple months ago. I expect it to be around for a couple more months.
